SPECIFICATION forming part of Letters Patent No. 363,824, dated May 31, 1887. Application filed November 27, 18H5. Serial No. 184 ,013. (No model.)

To all whom zit may concern-.-

Beit known that lI, JERA'MIAH HEAIVIL'IN, of Des Moines,.in the county of Polk and State of Iowa, have invented an Improved Washing-Machine, of which the following is a tom of the tub.

My improvement vconsists in the construction and combination of a detachable semicircular rubbing device with a detachable tubcover, a fixed metal frame, a driver-wheel, and a pinion and bolt in such a manner that the rubber can be raised and lowered relative to the clothing on the wash-board in the tub; in'the construction and combination of a perforated wooden circular wash-board with a metal frame, a circular plate, and screw-bolt,

f with the bottom of a tub in such a manner that the washboard can rotate horizontally -when the clothing is pressed-upon it by the reciprocating rubber, and also in such a manner that water can pass up and down through the wash-board and clothing .while the machine is in operation, all as hereinafter fully set forth, and pointed out-in my claims.

Figure l of my accompanying drawings shows a vertical central section of my machine. Fig. 2 shows my perforated circular wash-board in an inverted position. Fig. 3 is a top view of thc circular plate upon which the circular bottom rests and revolves. Jointly considered, these figures clearly illustrate the construction and operation of my complete in` vention.

A A represent the sides of a wooden tulov of common form mounted upon legs.

B B are curved ribs xed to the inside faces f n f of the tub in vertical positions,and with their convex sides toward each other in such a manner that they will aid in rubbing theclothing and agitating and circulating the Water .through the meshes ofthe fabrics that are rubbed in the tub.

C is a vertical extension atone of the ends of the tub adapted to support a wringer.

D D are portions of a xed top and cover that brace the sides and support the detachable cover.

F is a detachable wooden cover. lIt has an opening in its center, through which a pinion is passed.

G is a metal frame fixed on top of `the cover. It has an arched top and bearing, H, to support a drive-wheel, and a cross-piece, J, from which to suspend the reciprocating and adjustable rubber.

K is the metal portion of my rubber. It has a tubular vertical extension at its center and a pinion at the top of the extension formed integral therewith.

L is the wooden portion of the rubber, pret erably made of a single piece of oak and of a semicircular or U shape A screw bolt is passed upward through the vertical extension and pinion of the metal part K. A cavity is `formed in the wooden part L for the reception of the head of vthe bolt, andthe metal part then fixed on the convex side of thewooden part by means of screws, or in any suitable way, as shown in Fig. 1.

To adjustably A connect the rubber thus form ed with the cover I first place a nut on the screw-threaded end of the bolt that projects through the pinion, and then pass the saine end through a perforation in the part .Iof the frame G and place a nut upon the end of the bolt to retain it suspended in such a manner that it will serve as an axle around which the pinion and rubber K L can be circularly reciprocated by means of a segmental gear or driver, M, that is mounted in the bearing H and engages thepinion on the upper end of the tubular portion of the metal part K.-

N is a circular and perforated Wooden-washboard and platform, upon which clothing is rubbed by the reciprocating rubber.

l? is a metal frame fixed to the under side of 'the wooden board by means of screws, or in any suitable Way. It basa perforation in its center and a concentric circular groove.

R is a circular plate fixed in the center and on top of the bottom of thetub. It has a cirv cular bead that ts into the circular groove in the franie P, to aid in` keeping the complete IOO movable washboard in a central and level. pof sition.

S is a bolt that is passed through the frame' P before the frame is xed to the wooden of the tub, and then secure it by means of a nut, as shown in Fig. l, in such a manner that y it can be revolved upon lthe plate R, as required, to accommodate itself to the movements of the articles pressed and rubbed upon it.

From the foregoing description of the con-v struction and function of each part the practical operation of my complete machine is obvious. Y

I am aware that a tubular metal shaft having a square bottom and a pinion at its top has been fixed to the cross-bar of a dasher or rubbing device provided with adjustable extensions at its lower end, and that su'ch an extensible rubbing device has been combined with a bearer or frame lixed to a cover by means of a detachable screw-bolt anda single nut, to be suspended and rotated in reverse Ways within a tub; but my manner of con structing a rubber having a rod or screwbolt permanently connected therewith anud combining the complete rubber with a cover having an opening for the passage of the pinion on the end ofthe tubular shaft, and a metal frame and bearer fixed to the cover over the opening in such a manner that the complete rubber can be readily adjusted vertically relative to the cover without detaching the tubular shaft and pinion 'from the rubber, and advantageously operated without allowing the lower ends of the corrosive metal shaft and metal `bolt from coming in contact with the articles washed in the tub, is novel.

I am also aware that a perforated bottom or carrier has been pivoted in the bottom of a tub in various ways; but my manner of constructing a rotating wash-board by combining ametal frame and a Wooden board and a bolt so as to cover the metal frame and the bolt with the wood, and my manner of combining the complete rotating circular Wash-board with the bottom ofthe tub, so that its friction and motion can be regulated by means of a nut on the pivotal bolt, as required, to rub clothing4 upon its top surface, is novel and greatly advantageous.

I claim as my invention- 1. In a washing-machine, the metal frame K, having an integral tubular shaft and pin'- ion, the wooden frame L, having a cavity in its top surface, and a screw-bolt having its head inclosed in said cavity in the wood and its threaded end projected through said shaftand pinion, constructed and permanently' connected as shown and described, for the purposes stated.

2. The combination of the metal frame 41?,
